Topic: Which speed sensor?

[digitalferg]

I've just swapped in a tranny and tcase into my 02 Prerunner Tacoma from what I think was a 97 4runner (It was def a 4runner but have forgotten which year it was for sure...)

Question is this:  How do I figure out which VSS (speed sensor) to use since the 4runner tcase doesn't have one? (It has the spot, just has a cover bolted in it.)

At first, I thought just the same year Tacoma VSS as the 4runner tcase is from, but then after more reading, it sounds like the 96-97 4runners would take a mechanical style speed sensor in the tcase...  How do I tell if mine needs the mechanical speedo or the newer electric speedo?  And how do I tell how many teeth on the speedo gear I need to have?

Here's some pics if it helps....

get a speedo from a 98-99 taco 4x4 put it in that plug spot and extend that plug to it..

if that sounded confusing ill rephrase...put an electric vss in the the hole that is plugged and extend your wiring to it

Thanks for the replies.  The old tranny was a 2wd--I've converted my Prerunner Tacoma to a 4WD.

So after making a thread on this on several sites, I didn't find any exact info on how to tell other than peak through the hole and count the teeth, which is a difficult task when the case is already on the truck... And which still didn't tell me whether or not mine took a mechanical one or an electric one, but in a few helpful threads, most seemed to think mine should take the electric one.

Soooo.... I made a crazy decision and just bought a random speed sensor on ebay. I found one marked as from a 98 4x4 4cyl A/T. It was marked as 11/32.

When I got it, first step was to see if it fit into the case--and it fit perfectly! Next step was to extend the wiring ~12 inches or so.

Once done and connected, I fired up the truck and took her for a spin and--Voila! Miraculously, I have a working speedo again!

Now just gotta figure out how close to actual speed it is getting me....

Thanks for all the help!
